Diagnostic Testing & Imaging

Gain insight into your specific condition.

Innovative Services That Give You Answers

Our ThedaCare Cardiovascular Care team uses the latest technology to gain insight into your specific condition. We use a variety of non-invasive and invasive diagnostic options to evaluate and manage patients with heart disease and related conditions.

Depending on your symptoms and the needs of your body, the type of imaging will vary as directed by your doctor.

Common Diagnostic Tests

Cardiac CT Scans

A cardiac CT scan is an imaging test that looks at the arteries that supply blood to your heart. It may be done to diagnose the cause of chest pain or other symptoms.

CT Angiograms

Computed Tomography Angiogram (CT Angiogram) is a diagnostic test that provides detailed pictures of the heart and blood vessels. A CT angiogram can show narrowed or blocked areas of a blood vessel.

Stress Testing (Exercise, Nuclear Echo)

A stress test shows how your heart works during physical activity, and typically involves walking on a treadmill or receiving a medication that mimics exercise in your body. During the test, your heart rhythm, blood pressure and breathing are monitored by our cardiovascular team.


An echocardiogram is a non-invasive test that uses ultrasound waves to evaluate the heart’s valves and chambers.

Vascular Ultrasound

Vascular ultrasound is a non-invasive test that uses ultrasound waves to evaluate blood vessels, arteries and veins. 

Tilt Table Testing

A tilt table test attempts to determine the cause of fainting by creating changes in posture from lying to standing while connected to an EKG and blood pressure monitor. Our cardiovascular team monitors the process as it is taking place. 

Holter, Event and EKG Interpretation

Holter monitors, event monitors and EKGs evaluate and record the heart’s electrical activity including how fast the heart is beating, the rhythm of the heart beats (steady or irregular), and the strength and timing of the electrical impulses as they move through the different parts of the heart. 

Loop Recorder

An implantable loop recorder is a type of heart-monitoring device that records your heart rhythm continuously for up to three years. It records the electrical signals of your heart and allows remote monitoring by way of a small device inserted just beneath the skin of the chest.
